Polyester Imide Enameled Copper Wire
Polyester imide Enameled Copper Winding Wire Description
The insulation grade of polyesterimide enameled wire is 180. The product has good heat shock resistance, high softening breakdown temperature, excellent mechanical strength, and good solvent and refrigerant resistance. The disadvantage of polyesterimide enameled wire is that it is easy to hydrolyze under closed conditions. Polyesterimide enamel coated copper wire is widely used in windings of motors, electrical appliances, instruments, power tools, power dry transformers, etc. with high heat resistance requirements.

EIW is polyesterimide enameled wire. The heat resistance index is 180, and good modified products can reach the general level of 200.
General composite polyamide-imide, as a 200-level primer, has unsatisfactory salt water pinholes when applied alone.
High-temperature resistant enameled wire, as the name implies, is an enameled wire that can withstand high temperatures.
General enameled wires are temperature-resistant at levels 130 and 155, and those that can reach level 180 are already quite high.
High-temperature resistant enameled wires, in addition to the previous three specifications, can reach levels 200, 220, and even 240.
Each level means that this enameled wire can be used for a long time at that numerical temperature.
The maximum wire diameter of the product specification is 3.5mm, and the main products are QZY, QZY (XY), QY, etc.
